1 Claim. 1

Thisinvention relates to window sashes, is particularly concerned withwindow sash construction, ismore particularly concerned with a devicewhereby the sashes may readily beraised and lowered and wl'xereby thesashes may be ad justed at substantially any desired position, and isstill more particularly concerned with weather stripping to prevent coldair from entering into .the building, and is most particularly concernedwith runways disposed between the siderails of the sash and the sidemembers of the frame and adapted for the smooth movement of the saidsashes.

There are presently many window sash constructions to be had, and thereare many devices Vadapted for raising and lowering of window sashes.Howeven the devices presently had for raising and lowering, andadjusting sashes in position, rely principally on devices having sashweights. Sash Weights are not only unwieldy of installation but areextremely awkward of repair. Such devices are for other reasons quiteundesirable! It is therefore an object of the, present invention to`provide a sash construction. It is a further' object to provide'awindow sash construction whereby the sash may readily be raised andloW`- ered. It is a further object to provide a window sash constructionwhereby the sash may readily b adjusted in any desired position. afurther object to provide a window sash weather stripping. furtherobject of this invention is the provision of a window sash constructionhaving ease of construction and having economy of fabrication.

Y I have now discovered and invented in a window sash construction, aframe, an upper sash, a lower sash, two pairs of sash runways, each ofthe said sashes having a runway disposed on either side thereof, each ofthe said runways being interposed between the Side rails of each of thesashesand the said frame, the runways of each Side of the said framesbeing disposed back to back in respect to each other, a recess in eachside rail of each of the sashes being adapted for conforming of the saidrunways with the side rails of the said sashes, four coil springs, eachof the said runways an open space, each of the said spaces havinglongitudinally disposed therein the said space one of the said springs,each of the said springs being secured at their upper ends of the saidframe, the lower ends of each of the said springs being secured to thelower bottom rails of each of the two sashes, and the said springs beingarranged to hold the said It is still sashes in their adjusted position,and I amnow able to avoid the disadvantages of the prior art andamableto `accomplish the objects set forth.

Referring tothe drawings: I

Fig. 1 isan elevation View of la frame from the room side.

Fig. 2 is avertical section taken along the lines 2-2 of Fig. l.

Fig. 3` is a cross section view of the runways device into` which thesash conforms.

Fig. ris a horizontal section taken along Vthe lines 4-'4 of the Fig. l.i i

Fig. 5 is a vertical section taken along the lines V5--5 0f the Fig. 1.

` In 'the Fig. l the lower window pane I is setinto `the side rails 2,the bottom rail 3, and the inside meeting: rail 4. The upper window paneI is set into the side rails 2a, thetop rail of the upper frame, and`the lower inside meeting rail 5 of the upper frame. The numeral I3designates the vertical stops from the interior of the room, and thenumeral I4 designatesthe vertical stops from Athe weatherfside. `Thenumeral' designates the runway device for the lower sash. y

The Figi 2 isa verticalsecti'on taken along the line 22 of` Figfl, andshows the longitudinal right side'view of the runwayl device 8a for theupper sash. `The numeral @designates the coil spring `for the lowersash. The numeral I0 desig- -natesfthe coil spring for the upper sash.The clip Ia is formed from-the spring 9, andthe said clip I'Ilctv isheld over the `upper end of the run- `away 8. The cliplb is formed fromthe spring IIJ, and the said clip IIlb is held over the upper end of therunwayv 8a.

In the Fig. 5 is shown'the weather stripping 6 `set into` the rail 5,at` the meeting of ythe'said rail 5 and the rail 4. One edge of the saidweather stripping"J 5i iss'et .into alongitudinal groove formed in theframe 5, and the said stripping is frictionally held thereto by the saidframe.

In the Fig. 4 a cross section of the two runways are shown in smallscale, while in the Fig. 3 is shown a cross section of the runway inlarger scale. In the Fig. 4 the recess 1, cut into the side rails 2 andthe side rails 2a is shown.

The lower end of the spring 9 is secured to the thin steel bar I I. Thelower end of the spring I 0 is secured tothe thin steel ybar I2. Thesteel bars I I and I2 are nailed to the lower ends of the side rail 2,and 2a respectively.

Referring now to the Fig. 3 in which the larger cross sectional view ofthe runway is shown, the numeral I5 designates the outer side wall ofthe runway, the numeral I6 designates the inner window and side wall ofthe runway, and I1 the arch of the runway, which arch rests against themiddle of the side rails. The side rails of the sash are movable betweenthe members I5 and I6. The numerals I8, I9, and designate the flatsurfaces, and are merely a continuation of the member I6. The numeral 2ldesignates an angle continuation from the surface 20, and the edge bentupon itself. The numeral 22 designates the space in the runway forholding the spring 9, and the spring I0. The numeral 23 designates theopening between the member I6 and the angle 2I throughl which the barII, or bar I2, projects to engage the lower end of the spring 9 or thespring IIJ. The numeral 24 designates the edges of the arch I1.

4The window frame comprisesv the window sill 25, the under surface 26,and the two side frames. The lower sash is bordered at the bottom by thesill 25, and is bordered at each of its sides by each of a pair ofrunways 8 and 8a, disposed as shown in Fig..4. The springs 9 of thelower sash are disposed Within the space 22-of the runway,

and are secured at the top end by the clips IIIa, which clips are partof the springs, to the upper end of the runways. The lower end of thesaid springs 9 of the lower sash is secured to the bar I I.

I wish to point out that the structure of the. runway is specificallyfabricated and when seen from the cross section View as in the Fig. 3,the outer side wall is folded somewhat upon itself, the arch I1 issubstantially 80 degrees in respect to the said outer wall, the flatsurface I8 is substantially 90 degrees from the flat surface I9, the atsurface I9 is substantially 90 degrees in respect to the at surface 20,and the angle continuation from the surface 20, which is the secondouter wall is substantially 90 degrees from the surface 20.

I wishparticularly to point out that in the window sash construction ofmy invention there is great ease and economy of fabrication. The

runways may be constructed of light gauge sheet metal andthe machinerytherefore is very inexpensive -of construction. The assembly of therunways with Ythe rest of the window construction can be accomplishedwithout the need of any special machinery, and without the need of anyspecial skill;V an ordinary carpenter can make `the complete assemblywith ease.

making any necessary repair or replacement. I want further to point outthat great versatility of the construction is possible. The entireconstruction comprising the frames, sashes, and all other members may befabricated, assembled, or not assembled, in the plant, as it is mostconvenient to the builder or the fabricator.

The window construction of my invention may be used on any knocked-downwindow frame; and the frames can be'made sat the point of the cheapestmanufacture. The rabbeting on the side rails may be done at the point ofsale after the sashes have been assembled. There is no need for varyingtransverse sizes of runways since the runway of a given transverse sizeis adaptable for any window construction, and all that is necessary isto vary the length of the runways. To adjust for the varying weights ofwindow sashes, it is only necessary that the diameter of the spring wirevary from substantially 0.141 inches for the smallest and lightest sash,to 0.064 inches for the largest and heaviest sash. The length of thespring Varies according to the height of the component sashes.

I claim:

In a window sash construction, a sheet metal runway comprising a narrowouter wall, the said outer wall being substantially folded upon itself,an arched surface, the said arched surface extending therefrom the saidouter wall and the said arched surface being substantially eightydegrees in respect t o the said outer wall, an inner wall, the saidinner wall extending from the arched surface and formed by folding ofthe sheet metal upon itself, a flat surface, the said flat surfaceextending from the said inner wall, a second flat surface, the secondflat surface extending from the first at surface in a directionsubstantially ninety degrees from the first flat surf-ace, a third flatsurface, the third fiat surface extending in a direction substantiallyninety degrees from the second flat surface, a second outer wall, thesaid second outer wall being folded upon itself and extending from thethird ilat surface in a direction substantially ninety degrees from thesaid third at surface.
